APPARATUS FOR HEATING WAGON-TIRES.

Specification of Letters Patent N 0. 28,721, dated June 12 ,1860.

To all whom it may concern:

Be it known that I, ISAAC l WHITAKER, of Foreston, in the county of Ogleand State of Illinois, have invented a new and useful Device for Heating\Vagon-Tires; and I do hereby declare that the following is a full,clear, and exact description thereof, reference being had to theaccompanying drawings, forming a part of this specification, in whichFigure 1 represents a vertical longitudinal section taken through mytire-heater, showing in red lines tires of difi'erent sizes placedtherein and hung in such a manner as to be removed. The furnace, damperand smoke pipe are clearly shown in this figure, with arrows showing thedirection the currents of air take in passing through the heater. Fig. 2is a transverse vertical section taken through Fig. l as indicated bythe red line w, 00, marked thereon. This figure shows a nest of tiresarranged so as to be heated at one time.

Similar letters of reference indicate corre sponding parts in bothfigures.

To enable those skilled in the art to fully understand my invention Iwill proceed to describe its construction and operation.

In the drawings, A A represent two concentric cylinders of a suitablediameter, and made of cast-iron or other metal. These cylinders form acircular space, or tire box B, which is closed up with two rings orheads B, B, on each side, one of which heads is suitably hinged and canbe opened or closed at pleasure.

This apparatus is rested upon or it may form a part of the furnace D, ahole being cut through the outer cylinder, which is furnished with adamper E, for closing up this opening when necessary. The furnace D, isprovided with grate bars Gr, door and ash box, and it may have anopening similar to that indicated by a, in its end to which may beapplied the nozzle of a bellows for facilitating draught and thusheating up quicker.

In the top of the outer cylinder A, is a smoke pipe C, which conductsthe smoke, etc., ofi'like an ordinary smoke pipeoutside of the shop.

J, J, are serrated rollers equal in length to the width of the twocylinders, and having their bearings in the top part of and between thecylinders, as clearly shown by the drawings. Over these rollers J, J,the tires are placed, as clearly represented, the larger ones on thehighest roller, and the smaller ones on the lowest roller. The fire ismade in the furnace below, the cylinders are closed up tightly, and thefire heat and smoke all pass round the tires and impinge on the sameuntil it finally passes out through the escape pipe C, at the same timethe tires can be revolved while in their box and new surfaces thus bebrought in close proximity to the fire bed.

From this description it will be clearly seen that the old method ofheating tires and the objections attending the out-door fire areobviated. The apparatus may be used as a stove in the shop, at the sametime it will serve to heat tires-thus I obtain a great saving of fuel.The furnace and the circular box may be made of any suitable heatretaining material but cast-iron will be preferable and cheap and answerevery purpose.

Having thus described my invention what I claim and desire to secure byLetters Patent, is

The combination with the outer periphery of the tire box B, of thefurnace D, and smoke box C, when said tire box is arranged to standvertically as shown and is provided in its upper part with rollers J, J,by which the tires are suspended and rotated, all as herein set forthand represented for the purpose specified.
